PATHOLOGY

Detailed explanation-1: -The temperature in human testis is 2-3 degrees C less than that of body providing a suitable environment for sperm production. Pampiniform plexus play a major role in this.

Detailed explanation-2: -The epididymis (pronounced: ep-uh-DID-uh-miss) and the testicles hang in a pouch-like structure outside the pelvis called the scrotum. This bag of skin helps to regulate the temperature of testicles, which need to be kept cooler than body temperature to produce sperm.
